Abstract: A device treats a thread with compressed air. To this end, the device has an intermingling device which is encapsulated in a housing with respect to the environment. For thread guidance, the housing has a thread inlet and an opposite thread outlet. In order to prevent direct transmission of noise through the thread inlet and the thread outlet, the thread inlet and/or the thread outlet is formed in each case by two separate opening slots in quick succession and a thread guiding member between the opening slots.

Abstract: A method and a device for crimping a multifilament thread are described. The thread is blown by means of a transport nozzle through a compressed air stream guided in a thread channel into a gas-permeable compression chamber. Inside the compression chamber, the thread is compressed to form a thread plug, which is then continuously removed through an outlet of the compression chamber. The compression and the removal of the thread plug are monitored by measuring the pressure of the compressed air stream. According to the invention, a plurality of pressures of the compressed air stream in the compression chamber are measured at a plurality of measurement points distributed over the length of the compression chamber for monitoring the thread plug formation in order to perform the compressing and cooling of the thread plug with a uniform filling of the compression chamber.

Abstract: An apparatus for continuously winding up a thread is described and includes two winding spindles that are held in a projecting manner on a rotary table and are associated with spindle drives to allow the thread to be alternately wound to form a bobbin. The rotary table can be activated in order to exchange the winding spindles between a winding region and a changing region. A moveable changing device transfers the thread between the winding spindles and during the exchange of the winding spindles, guides the thread between the winding spindles for transferring to a catching device on one of the winding spindles. The changing device has at least one deflecting thread guide and a movable feeding thread guide, which can be positioned in a deflecting position, the thread being guided at a distance from the winding spindle which receives the thread.

Abstract: A method and a device for producing a crimped multifilament thread are described. A multiplicity of filaments are extruded by means of a spinning machine, cooled and subsequently treated by a drawing device and a crimping device to form a crimped thread. Before the thread is wound up to form a bobbin, a multiplicity of intertwining knots is produced on the crimped thread by a treatment device. In order to obtain defined patterns of the intertwining knots within the thread, a pulse sequence of compressed air pulses at a predefined frequency is directed at the thread. The treatment device has a controllable blowing means.
